Now unity 5 did some things as well (not playmaker related but may help others).

After the upgrade to unity 5, 'master Audio' had issues. unity 5 defaults to 2d/3d audio NOT at the source any more. So the audio was not heard as it became 2d. had to change those in the master audio prefab.

Also, some of my assets (tanks, planes) would not move. Turns out that some of the items were changed to 'static'. had to uncheck those in the scenes and project folder prefabs.

Had "MissingMethodException: Method not found: 'UnityEngine.Component.get_guiTexture" exception as well. Turns out there were some leftovers from previous version of PlayMaker.So what I did is I created an empty scene, so my references wont mess up. Then I deleted Playmaker folder and closed Unity. Made sure nothing stayed of PlayMaker in my assets and then reopened Unity and reimported everything. So far - no problems.

Are Arrays using the Arraymaker actions? I had them before the update so I'm not sure, I couldn't see any other reference to arrays.

Every object with a Playmaker FSM is throwing this error: MissingMethodException: Method not found:'UnityEngine.Component.get_guiTexture'.

And these are constantly piling up at runtime: Bad ErrorCheck: HutongGames.PlayMaker.Actions.TriggerEventUnityEngine.Debug:Log(Object)HutongGames.PlayMakerEditor.FsmErrorChecker:CheckActionForErrors(FsmState, FsmStateAction)HutongGames.PlayMakerEditor.FsmErrorChecker:DoCheckFsmForErrors(Fsm)HutongGames.PlayMakerEditor.FsmErrorChecker:DoCheckForErrors()HutongGames.PlayMakerEditor.FsmErrorChecker:Update()HutongGames.PlayMakerEditor.FsmEditor:Update()FsmEditorWindow:Update() (at Assets/PlayMaker/Editor/FsmEditorWindow.cs:319)UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

Also is the new UI stuff seperate? that's not in my action browser either.

PlayMaker 1.7.8 doesn't have builtin arrays ( it's coming with 1., so if you have arrayMaker, yes, there is a set of specific custom actions to go with ArrayMaker so you can work with ArrayMaker lists and hashtables proxies.

ArrayMaker is a separate package from the wiki, not an official package.

Is this the only error you get, you have no other errors ( different errors, not repeatably the same one I mean)

Just wanted to share that I'm also getting the following error for any GameObjects with a FSM on in upgraded projects:Method not found: 'UnityEngine.Component.get_guiTexture'.

I followed user Caenhorn's suggested fix which worked and stopped all the errors.1 - create and save a new scene2 - take a copy of my global variables file3 - delete the the entire playmaker folder in the project4 - close unity5 - open unity and import playmaker back into the project6 - paste my global variables file back in7 - added playmaker editor back into the editor

Jean, I hope this helps in some way to track the problem down.And thank you Caenhorn for your suggested fix!

Having a strange problem with WWWObject action. Playmaker tells me an object with an FSM that accesses WWWObject can't be created and 'maybe the script was removed' but the WWWObject script is in the Actions folder.
